Bad Alloc

[ahmed-shafik]

Dears,

I get the below error while creating a new rank object because of adding new bankstates (nextWrite_H & nextRead_H) in BankState.h and BankState.cpp. Do you know why?

class BankState { ostream &dramsim_log; public: //Fields CurrentBankState currentBankState; unsigned openRowAddress; uint64_t nextRead; uint64_t nextWrite; uint64_t nextRead_H; uint64_t nextWrite_H; uint64_t nextActivate; uint64_t nextPrecharge; uint64_t nextPowerUp;

BusPacketType lastCommand;
unsigned stateChangeCountdown;

//Functions
BankState(ostream &dramsim_log_);
void print();

}; }

//All banks start precharged BankState::BankState(ostream &dramsim_log_): dramsim_log(dramsim_log_), currentBankState(Idle), openRowAddress(0), nextRead(0), nextRead_H(0), nextWrite(0), nextWrite_H(0), nextActivate(0), nextPrecharge(0), nextPowerUp(0), lastCommand(READ), stateChangeCountdown(0) {}

Rank *r = new Rank(dramsim_log); terminate called after throwing an instance of 'std::bad_alloc' what(): std::bad_alloc Aborted (core dumped)

I used gdb and get below (_n=18446744073709547290) after statement return size_type(this->_M_impl._M_finish - this->_M_impl._M_start) although in normal state the (n=2048). Do you know why ?
